The invention relates to a method and a device for generating a two-dimensional light field image, and the two-dimensional light field image is used for cooperating with a pinhole array to present a three-dimensional light field of a virtual three-dimensional model. The method comprises the following steps: acquiring a target object image resolution D1 of the three-dimensional light field, a design distance S between the pinhole array and a two-dimensional light field image to be generated, a target visual angle theta of the three-dimensional light field and a target image resolution D2 of thetwo-dimensional light field image; determining geometric parameters of a two-dimensional image surface where the two-dimensional light field image is located; dividing the two-dimensional image surface into an object image grid array according to the target object image resolution D1; calibrating the relative positions of the virtual three-dimensional model and a virtual pinhole array corresponding to the pinhole array;
